Nonadiabatic Electron Pumping: Maximal Current with Minimal Noise
The noise properties of pump currents through an open double quantum dot
setup with non-adiabatic ac driving are investigated. Driving frequencies close
to the internal resonances of the double dot-system mark the optimal working
points at which the pump current assumes a maximum while its noise power
possesses a remarkably low minimum. A rotating-wave approximation provides
analytical expressions for the current and its noise power and allows to
optimize the noise characteristics. The analytical results are compared to
numerical results from a Floquet transport theory.Comment: 4 pages, 3 figures, replaced Fig. 1, added new inset in Fig. 2,

Rotating filters permit wide range of optical pyrometry
Gear-driven dual filter disks of graduated density vary linearly with respect to rotation, allowing a wide range of photographic pyrometry. this technique is applicable in metallurgy, glass, plastics and refractory research, and crystallography
